About the company

SunnyMac provides turnkey solar energy solutions for homes and businesses in the Mid-Atlantic. It designs, installs, and maintains photovoltaic solar systems, offering roof-mounted and ground-mounted panels, solar battery storage, and EV charger installations. The company handles every step of a project—from initial consultation and custom design to permitting, installation, and ongoing maintenance—backed by a 25-year warranty on the entire system (panels, inverters, and mounting hardware). It works with manufacturers such as Tesla, Enphase, SolarEdge, and Q Cells, and previously served as an installation partner for larger firms before returning to comprehensive EPC services. SunnyMac differentiates itself by managing complete projects in-house as a single-source energy solution provider rather than relying on external partners. The goal is to help customers generate clean energy, lower utility costs, and enjoy a hassle-free, holistic home energy system across the Mid-Atlantic region.
